Southborough is a town immediately north of Tunbridge Wells, centred on its 71-acre common and known for its cricketing heritage.

Southborough lies immediately north of Royal Tunbridge Wells. After the Norman Conquest the area was known as the South Borough within the domain of Tonbridge Castle, and the town separated from Tonbridge in 1871. It became an urban district in 1894 and a civil parish in 1974, and today it has its own Town Council. The town has a long cricketing tradition: cricket has been played on the common for over 200 years, and it was once a centre of cricket ball manufacture.

Southborough Common covers 71 acres and sits on the north-western edge of the town. It combines ancient woodland, wood pasture, relic heathland and an old quarry, with veteran oak, beech and birch trees. Bluebells appear in spring and a wide range of fungi in autumn. The Kent High Weald Partnership and local volunteers have created three self-guided walking routes across the site. Holden Pond is another local landmark.

The A26 runs through the town. The High Brooms district has its own railway station with services towards London and Hastings.
